The double resonances of magnetism and solid coupling of hydroelectric-generator stator system

A double-shell model of hydroelectric-generator stator system was establish ed. Applying the theory of mechano-electric analytical dynamics theory, the nonlinear vibration equation of magnetism and solid coupling of hydroelect ric-generator stator system, under steadily balanced three-phases operating condition, was obtained. According to the method of multiple scales for no nlinear oscillations, the double resonances of magnetism and solid coupling of hydroelectric-generator stater system, were investigated. It is pointed out that the system has abundant dynamics phenomenon including the attenda nt jumps and coexistence of multiple stable motions.
